Steelers quarterback Ben Roethlisberger had an MRI on his knee on Tuesday morning after the team returned from San Diego and the results were the same as what the team heard following the game.

Roethlisberger has a hyperextended knee and a bone bruise and has not been ruled out for Sunday’s game against the Jacksonville Jaguars at Heinz Field.

“We’ll see how the week progresses,” said head coach Bill Cowher. “I think we all have a deep sigh of relief in regards to the prognosis.”

Roethlisberger suffered the injury in the final minute the 24-22 win over the Chargers. Charlie Batch came in and handed the ball off for the final few plays, before Jeff Reed sealed the win with a field goal.

Batch could be called upon again this week, depending on how the injuries to Roethlisberger and back-up Tommy Maddox progress this week.

“Based on the information I have right now, Charlie Batch is the starter by default until I see more.”

Maddox suffered a calf injury in practice on Friday and did not make the trip to San Diego. Maddox was at the team’s practice facility on Tuesday morning, and his prognosis seems better than expected as well.

“When he got injured on Friday we thought it was a lot like Jerome (Bettis) in terms of the extent of it,” said Cowher. Tommy came in this morning and felt pretty good. I think he is going practice tomorrow. There is a good chance he will be available this week as well.

“The dire situation we thought coming in this morning doesn’t appear that right now.”

The Steelers do not plan any major roster moves at this time based on the injuries, but will add former Pitt quarterback Rod Rutherford to their practice squad.

The other injury from Monday night’s game in San Diego was to cornerback Ricardo Colclough. Colclough suffered a shoulder injury and will miss Sunday’s game against Jacksonville

congrats, they squeaked out a win but in the process Big ben is out for a bit, and the offense is beat up a little more, I wonder how many will make it to seasons end, anyone else notice that "the bus" is beginning to look and move a bit more like "the fridge"
